Subaru's horizontally-opposed 2.0-liter four cylinder diesel engine is the first of its kind. First revealed in the Outback/Legacy range in Geneva earlier this year, Subaru is now debuting the engine in Paris this October in two of its other models, the Impreza 5-door hatchback and Forester SUV.

Both the Forester and Impreza Boxer Diesels feature new six-speed manual gearboxes while the engine receives a new closed-type diesel particulate filter.

Subaru states the Forester 2.0D boasts class-leading fuel economy and emissions with 44.8 mpg combined and 167 g/km.

The Forester 2.0D produces 147 PS and 258 lb ft torque and the Impreza 150 PS and 258 lb ft – both at 3,600 rpm and 1,800 rpm respectively.

The new Forester Boxer Diesel goes on sale in the UK in late September and the Impreza Boxer Diesel in January 2009.
